$subject = $_POST['subject'];
$message = $_POST['message'];
echo $subject, " from ", $name, " at ", $from, "<br/>";

$retval = mail( $to, $subject, $message );
推荐答案
根据您的评论，您尝试使用通过Gmail服务器将邮件传递到 oblivy.com 。除非您是已注册并经过身份验证的用户，否则Google绝对不会允许这样做。接受来自匿名方的任何目的地的消息的服务器称为开放中继：
As per your comments, you're trying to use Gmail server to deliver messages to oblivy.com. Google will never allow that unless you're a registered and authenticated user. Servers that accept messages from anonymous parties for any destination are called open relays:
开放式中继（有时称为不安全中继或第三方
中继）是SMTP电子邮件服务器，它允许第三方
电子邮件的聚会中继。通过处理既不是发给本地用户又不是来自
本地用户的邮件，开放中继可以使不道德的发件人
路由大量垃圾邮件。实际上，服务器的所有者（通常不知道问题的
）将网络和
的计算机资源捐赠给发件人。除了垃圾邮件发送者劫持服务器时产生的
财务成本外，
的组织还可能遭受系统崩溃，设备损坏以及
的业务损失。
An open relay (sometimes called an insecure relay or a third-party relay) is an SMTP e-mail server that allows third-party relay of e-mail messages. By processing mail that is neither for nor from a local user, an open relay makes it possible for an unscrupulous sender to route large volumes of spam. In effect, the owner of the server -- who is typically unaware of the problem -- donates network and computer resources to the sender's purpose. In addition to the financial costs incurred when a spammer hijacks a server, an organization may also suffer system crashes, equipment damage, and loss of business.
它们在1990年代后期成为问题，并且创建了开放中继的黑名单，因此邮件服务器管理员可以拒绝来自此类服务器的任何传入邮件。
They became a problem in the late 1990s and blacks lists of open relays were created, so mail server administrators could just reject any incoming mail from such servers.
因此，您需要创建一个Gmail帐户并在发送邮件时提供其凭据。此外，如果启用了双重身份验证，则还需要在此处使用专用的应用程序密钥（而不是常规密码）。
Thus you need to create a Gmail account and provide its credentials when sending mail. Additionally, if you enable two-factor authentication you also need a dedicated application key to use here (instead of your regular password).
并通过身份验证发送电子邮件支持SMTP-AUTH（以及可能的加密）的完整邮件库。旧的 mail（）没有。
And to send email with authentication you need a full-fledged mail library that supports SMTP-AUTH (and possibly encryption). Good old mail() doesn't.
